Absolutely, there are charges per hour for this and you may want to purchase another wiring harness instead of removing the old harness. This would be least time consuming and by keeping the wiring harness in the other vehicle you may want to transfer the unit back and forth between vehicles.
GPS signals available to civilian GPS receivers can be used to compute position to within 10 meters most of the time. However, the precision of the GPS signals is sometimes intentionally diluted in certain sensitive areas based on national security needs.
GPS signals are available all over the world. However, please note that GPS receivers need signals from three or more satellites to compute position and, in general, this requires that an antenna connected to the GPS receiver be placed with a clear view of the sky. GPS reception may be inconsistent in certain locations or under certain conditions, such as:
(a) Indoors, in parking garages, etc.
(b) Under heavy foliage
(c) Urban canyons, near tall buildings, etc.
(d) Extreme weather conditions

Automatic vehicle location (AVL or ~locating; telelocating in EU) is a means for automatically determining the geographic location of a vehicle and transmitting the information to a requester. While GPS positioning and wireless communication services are used in the most common implementations, AVL is also implemented using GSM, RFID, or RTLS.
Most commonly, the location is determined using GPS, and the transmission mechanism is a satellite, terrestrial radio or cellular connection from the vehicle to a radio receiver, satellite or nearby cell tower. Other options for determining actual location, for example in environments where GPS illumination is poor, are dead reckoning, i.e. inertial navigation, or active RFID systems or cooperative RTLS systems. With advantage, combinations of these systems may be applied.
After capture, the tracking data is transmitted using any choice of telemetry or wireless communications systems. GSM and EVDO are the most common services applied. Because of the low data rate needed for AVL, and the low cost and near-ubiquitous nature of these public networks. The low bandwidth requirements also allow for satellite technology to receive telemetry data at a moderately higher cost, but across a global coverage area and into very remote locations not covered well by terrestrial radio or public carriers. One system description discloses that locations are polled every thirty seconds.
Application with vehicles
Automatic vehicle locating is a powerful concept for managing fleets of vehicles, as service vehicles, emergency vehicles, and especially precious construction equipment, also public transport vehicles (buses and trains). It is also used to track mobile assets, such as non wheeled construction equipment, non motorized trailers, and mobile power generators.
Application with vehicle drivers and crews
The other purpose of tracking is to provide graded service or to manage a large driver and crewing staff effectively. For example, suppose an ambulance fleet has an objective of arriving at the location of a call for service within six minutes of receiving the request. Using an AVL system allows to evaluate the locations of all vehicles in service with driver and other crew in order to pick the vehicle that will most likely arrive at the destination fastest, (meeting the service objective).

Global Positioning System satellites transmit signals to equipment on the ground. GPS receivers passively receive satellite signals; they do not transmit. GPS receivers require an unobstructed view of the sky, so they are used only outdoors and they often do not perform well within forested areas or near tall buildings. GPS operations depend on a very accurate time reference, which is provided by atomic clocks at the U.S. Naval Observatory. Each GPS satellite has atomic clocks on board.
Each GPS satellite transmits data that indicates its location and the current time. All GPS satellites synchronize operations so that these repeating signals are transmitted at the same instant. The signals, moving at the speed of light, arrive at a GPS receiver at slightly different times because some satellites are farther away than others. The distance to the GPS satellites can be determined by estimating the amount of time it takes for their signals to reach the receiver. When the receiver estimates the distance to at least four GPS satellites, it can calculate its position in three dimensions.
There are at least 24 operational GPS satellites at all times. The satellites, operated by the U.S. Air Force, orbit with a period of 12 hours. Ground stations are used to precisely track each satellite’s orbit.
The Global Positioning System (GPS) is a constellation of satellites that orbit the earth twice a day, transmitting precise time and position (latitude and longitude) information. With a GPS receiver, users can determine their location anywhere on Earth. Detailed mapping and navigational programs can be used in conjunction with GPS technology to track the movement and location of vehicles and assets.
The system consists of 24 satellites orbiting about 12,000 miles above the Earth and five ground stations to monitor and manage the satellite constellation. These satellites provide 24-hour-a-day coverage. A GPS receiver on or above the Earth’s surface picks up at least three satellite signals simultaneously and uses these signals to determine exactly how far your GPS receiver is from the GPS satellites in space. It is then possible to pinpoint its exact location on earth. This is known as Triangulation.
GPS vehicle tracking systems use the Internet as an interface to allow you to control your GPS system, while wireless & cellular technologies are utilized to send and receive GPS requests and location information to and from the vehicle.
There are no GPS systems of this type that give 100% coverage, the vehicle could be out of cellular range or parked in a garage impacting GPS signals. Climate and atmospheric conditions can also impact GPS requests and responses. Wait a few minutes or wait till climate conditions are better and try again. Also consider, the driver may be temporarily residing in a low-cellular signal area.
We offer several types of GPS devices, each one with its own features. Depending on the specific usage and objectives you are planning, some devices will perform better than others. We have a highly qualified group of senior GPS Tracking consultants who will be more than happy to help you in selecting the most appropriate GPS device. Please contact us to help you!
A “Real-Time” system generally utilizes wireless networks to allow you to receive the information and view the location of your asset in “real-time”. In most cases, response time and location information can result in delays up to 30-second to 1-minute. Real-Time tracking is becoming the industry standard for vehicle and asset tracking. Features include, on-demand location, speed, and direction.
A “Passive” system generally is limited to vehicle tracking applications only. With a “Passive” system, the location data is stored and downloaded from the vehicle at the end of the day, or when the vehicle returns. Passive systems are used when companies do not need to view their fleet in real-time or have the need to receive alert notifications for speed violations, zones and other features that real-time systems offer.
